the dlib GUI was used.

Steve Taylor bf38cba574 Implemented a numerical quadrature method based on an adaptive 
Simpson rule.  Added unit tests and supporting examples for this
function.

Davis King a8d7374414 Added point_transform_projective and find_projective_transform() 2013-05-19 20:16:57 -04:00
Davis King 6e2a867a37 In a recent commit I added per label bias features but forgot to exclude them 
from the non-negative feature learning range.  This change fixes that.

Davis King 6989e96f7d Added per label bias features. 2013-05-18 15:16:30 -04:00
Davis King e2ea6cfaac Added additional validation to serialized sequence_segmenter objects. This 
should help catch the case where a user changes the feature extractor and then
tries to load an old model.

Davis King cd319ec522 updated docs 2013-05-04 12:52:03 -04:00
Davis King 0cdbbe85ec Added the svr_linear_trainer. 2013-05-04 12:44:30 -04:00
Davis King 73551a87c6 This is a minor change. All it does is slightly change the stopping condition 
used by the svm_c_linear_trainer so that the epsilon value is not implicitly
scaled by the C values given by the user.  This should make this object
slightly easier to use.
